Abstract
The utility model relates to a transformer which comprises a shell body. A magnetic core is arranged in the shell body, a temperature detecting device is arranged on the inner side of the shell body, and the temperature detecting device is connected with a temperature early warning device. According to the transformer, the temperature of the transformer in the operating process can be effectively detected, once the temperature exceeds a preset temperature, an alarm is given, and the situation that when the transformer operates with overload for a long time, a coil is hot, an insulation layer is gradually aged, an inter-box short circuit or an interphase short circuit or a grounding short circuit and oil decomposition are caused is avoided.
Description
Technical field
The utility model relates to a kind of transformer.
Background technology
Transformer is to utilize the principle of electromagnetic induction to change the device of alternating voltage, and main member is primary coil, secondary coil and iron core (magnetic core).In electric equipment and radio-circuit, transformer is commonly used for lifting voltage, matched impedance, safety isolation etc.In generator, no matter be that coil movement is passed through magnetic field or Movement in Magnetic Field by fixed coil, all can be in coil induced potential.
If transformer, when long overlond running, can cause coil heating, make insulation aging gradually, cause the decomposition of short circuit between casket, phase fault or shorted to earth and oil.In prior art, do not design and a kind ofly detect the temperature of transformer in running and produce the device of early warning.
Utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of transformer is provided.
The utility model is to be achieved through the following technical solutions:
A transformer, comprises that housing, described housing are built-in with magnetic core, and described housing inner side is provided with temperature-detecting device, and described temperature-detecting device connects temperature pre-warning device.
Further, described housing is for being with gelled rectangular box.
Further, described temperature pre-warning device is arranged on the top cover of housing.
Further, described temperature-detecting device comprises transducer and microprocessor.
Compared with prior art, the beneficial effects of the utility model are: the utility model can detect the temperature of transformer in running effectively, once exceed the temperature of setting, to produce warning, prevent that transformer is when long overlond running, cause coil heating, make insulation aging gradually, cause the decomposition of short circuit between casket, phase fault or shorted to earth and oil.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of transformer, comprise that housing 1, described housing 1 are built-in with magnetic core 2, described housing 1 inner side is provided with temperature-detecting device 3, described temperature-detecting device 3 comprises transducer and microprocessor, described temperature-detecting device 3 connects temperature pre-warning device 4, described housing 1 is for being with gelled rectangular box, and described temperature pre-warning device 4 is arranged on the top cover of housing 1.
The utility model can detect the temperature of transformer in running effectively, once exceed the temperature of setting, to produce warning, prevent that transformer is when long overlond running, cause coil heating, make insulation aging gradually, cause the decomposition of short circuit between casket, phase fault or shorted to earth and oil.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
